How to Prepare for Wildfire Season & Help Protect Your Indoor Air Quality

As wildfire season grows longer and more intense across many regions, it’s not just the outdoor air we need to worry about. The smoke, soot, and fine particles generated by wildfires can seep into homes and commercial buildings, significantly reducing indoor air quality (IAQ). For individuals with allergies, asthma, or other respiratory sensitivities, poor IAQ can worsen symptoms and create uncomfortable or even unsafe living and working environments.

At DUCTZ, we understand how important it is to take proactive steps to protect the air you breathe—especially during wildfire season. Here are expert-backed tips for safeguarding your indoor air and how our indoor air quality services can support your efforts.

How Wildfires Impact Indoor Air Quality

Wildfire smoke contains a mix of harmful pollutants, including fine particulate matter (PM2.5), volatile organic compounds (VOCs), and other airborne contaminants. These particles are small enough to infiltrate buildings through windows, doors, and HVAC systems, where they can linger long after the flames are gone.

For people with asthma, allergies, or other health concerns, breathing in wildfire-related pollution indoors can increase symptoms such as coughing, wheezing, or difficulty breathing. Even individuals without chronic conditions may experience discomfort or irritation if indoor air is not properly filtered or maintained.

So what can you do to help combat this if you are in an area prone to wildfires or residual wildfire smoke? Let’s explore some proactive measures you can take. 

Prepare & Maintain Your HVAC System

Your HVAC system plays a critical role in protecting your indoor air from outdoor pollutants. But during wildfire season, it can also become a pathway for smoke and debris—especially if it hasn’t been properly maintained.

Here’s how to help keep it working in your favor:

• Upgrade to high-efficiency filters.
• Replace filters frequently—especially during periods of heavy smoke.
• Have your air ducts professionally cleaned to help remove built-up dust, debris, and other allergy triggers.
• Consider using stand-alone air purifiers to supplement your home’s filtration system.

DUCTZ provides home air duct cleaning and condenser coil cleaning services designed to support cleaner, healthier air—especially during high-risk seasons.

Create a “Clean Room” at Home

The Environmental Protection Agency (EPA) recommends setting up a “clean room” to help protect yourself during periods of poor air quality. This space should be sealed off from smoke and have enhanced filtration to help reduce exposure to wildfire-related pollutants.

Tips for setting up your clean room:

• Choose an interior room with as few windows and doors as possible.
• Use a portable air cleaner with a HEPA filter to help reduce airborne particles.
• Keep doors and windows closed, and seal any gaps with weather stripping or towels.
• Avoid indoor activities that can contribute to poor air quality (e.g., frying food, burning candles, vacuuming without HEPA filters).

Tips for Commercial Properties

Businesses, schools, and commercial facilities face unique challenges during wildfire season—particularly when it comes to large-scale HVAC systems and frequent foot traffic. Here’s how to help prepare:

• Schedule routine maintenance for rooftop units and air handlers.
• Upgrade air filters and replace them regularly.
• Schedule ductwork inspections and cleanings, especially if your building hasn’t had service in a while.
• Consider service during off-hours or breaks (like summer for schools) to minimize disruption.
